I know most use plywood for stringers, but would it be okay to use 2x3's? If I found straight 2x's and ripped them in half length-ways to make two stringers out of each 2x? My reasoning is that the distance from transom to blukhead is just over 9 feet. If I used plywood, I'd have to two-piece each length. 2x's, I could get in 10 footers. The picture below shows where a 2x4 and a 2x3 ends up height wise. The 2x3 would be perfect. With a 1/2" sole it would leave a slight lip to avoid any water flowing into the front area. There will be cut-outs at the bottom of the bulkhead to allow any water in the hatch area to flow under the sole to the bilge......thats the plan anyway. Other than a slight weight difference, what are the cons to using 2x's? Flex? Is 3 inches going to be enough height for the stringers? Thanks.
